I think we really need to start thinking in terms of what to show on the
display on the various "screens" we're featuring.

We currently have no displaying of what the F1-F3 keys do. We have no
vertical sliderbar in the directory browser, we have no volume indicator
visible, we have no status display showing when playback is paused (or key
lock or mute) etc.

I'm not saying that I miss anything of this, but I guess that some people
consider these to be flaws.

I would suggest that we spare, say F3, to toggle these fancy-display-things
on/off so that we can have maximum screen space for real info if we want to,
and then we can hit F3 to get the 'F-keys' and 'status line' and 'slide bar'
appear on screen.
